So we started from
something that worked
(Portland TriMet data
dump), and created the
Google Transit Feed
Speciﬁcation (GTFS)

17.
It’s CSV; easy to
understand, and maps
well to the DB table-
oriented workﬂow that
agency IT staff are
familiar with

18.
It’s an open format, and
its further development
is decided by the
community of users.

19.
The agencies prepare
these feed and put them
on their server for
Google to retrieve... but
they’re also usable by
other developers if the
agency is willing
